What is Biostatistics
Biostatistics is a term combining two words; biology and statistics. It is used to refer to the application of the statistical techniques to scientific research in health-related fields. Statistical methods are applied in various biological sciences which include biological laboratory experiments, medical research, health services, epidemiology, etc. Statistics is one of the best studies which can be applied in biological science for collection, summarization and analysis of data. Statistical application in biological sciences has had an immense impact on how genes are studied.
Students taking biostatistics have to be efficient in biology, mathematics, and statistics. Data statisticians analyze data with an aim to improve the present health conditions, conduct studies on vaccinations, emergency health service, and other critical health issues, and lastly, they collect information and data for identifying diseases and working on possible treatments. By applying suitable analysis or statistical methods to the medical data, one can identify and develop appropriate treatments for disease, and also the effect of such treatment on subjects can be examined. In addition, the biostatisticians identify risk factors for diseases and design, observe, analyze, interpret and produce a report based on results of clinical studies.
Various statistical methods are available to address queries arising from the data related to medical or public health issues. The most popular analysis used in the field of biological and health-related problems is Correlation, Regression, Logistic Regression, Odds Ratio, Chi-square statistic, Discriminant Analysis, Survival Analysis, and so on.

4 Things to remember when writing a Biostatistics assignment
- Bio-statistics is simply statistics in the medical and public health field. Care must thus be taken while deciding upon the statistical test to be applied over a particular problem.
- Sample selection must be suitable to the nature of the research problem without any discrepancy.
- Proper specification of the parameters from the population is important in regard to the research problem.
- The inference drawn needs to be of high practical significance
